Bull Moose Party

The Progressive Party, better known as the Bull Moose Party, was a progressive and nationalist political party in the United States that existed from 1912 to 1916. The party was founded by Theodore Roosevelt, who was disappointed with the transformation of the US Republican Party from a liberal party into a conservative party under William Howard Taft. Roosevelt ran for President in 1912 with California governor Hiram Johnson as his running mate, winning Washington, eleven of California's electoral votes, South Dakota, Minnesota, Michigan, and Pennsylvania. The party dissolved in 1916 after failing to win public offices, and the Republicans were left as a conservative party.
